Build Description
Build is possibly AFKable with 1.5k-2k stats, with repairs. 5 DU to spare (and it is possible that the Buff Beams could be shortened if you stack the minions close enough together). Do what you wish with these.
Hint 1: Mage Minions should have enough range to heal both sets of minions on each side.
Hint 2: 2 Archer Minions per buff beam.
